Product Summary

Angle Cock valve is a kind of manually operated ball valve, which runs in the I.D. of drilling, and it is one of effective tool for preventing from blowout.

The Angle Cock valve can be divided into upper Kelly cock valve and lower cock.The upper Kelly cock is connected between lower ends of swivel and upper end of Kelly. The lower cock is connected between upper end of drill pipe and lower end of Kelly or connected between lower ends of Kelly saver subs. The Angle Cock valve features a simple operation. It can be opened on or closed off by only turning the special operating spanner at 90 degrees according to indication direction. During drilling operation, in order to avoid serious well kick or blowout accident, the cock shall be connected at upper end and lower end of it.

Angle Cock valve is a type of the poppet valves. When the poppet is moved toward the top of the valve, the internal body cavity is open to the system and flow is unimpeded (maximum conductance). Once the actuator moves the poppet to the bottom of the valve an elastomeric sealing ring is compressed onto the sealing surface of the lower body of the valve. This action creates a vacuum tight seal and stops the flow. Angle Cock valve is suitable for vacuum applications with venting processes , high vacuum applications in pumping systems, semiconductor technology, research systems, etc.
